circulation/ bicycle

Although energy has all kinds of forms, it always comes from somewhere and will not vanish anyhow. It just transforms to another existence. The idea of Circulation is an energy adjustment medium mounted on the bicycle, which transforms the consumed human energy of riding bicycle into practical energy for bicycle riders. The idea of Circulation is to store and control the mechanical energy, which comes form both potential and kinetic energy, with clockwork device during the energy transformation process. Then, the stored energy will feed back to the rider.
